- Extremely flexible bonding with no additional limitation on

- Works with existing CMTS hardware

- Uses DOCSIS 3.0 framework for channel bonding

800-DMIPS CPU with advanced memory architecture

- Delivers unprecedented data rates

- High-speed DDR266 interface with support to 64 MB

- Read-ahead cache (RAC) and low-latency DRAM access

16 SIDs provide capability for superior QoS performance and

simultaneous high QoS and BE traffic.

Secure boot loader and authentication protect against

malicious software uploads and service theft.

Flexible expansion with PCI support allows for Gigabit

Ethernet connectivity, voice, wireless, gateway, storage, or

other peripherals.

SmartSpectrum delivers multiple dB enhanced robustness in

noisy plant conditions.

Propane packet acceleration improves throughput and

efficiency up to three times.

TurboQAM leads to over 30% increased upstream and

downstream performance.

Ninth-generation technology ensures a proven, robust, and

reliable solution.
